To all rollo/m it may concern:

4ths, Sths, iths, and 32ds of an inch, While Be it known that I, JOHN A. Oaarsrnon,

l l the scales C on the long arm A have as a citizen of the United States, i.; a resident l units 2 thirds, 3ds, ths, 12ths, and 24ths of the city of N ew York, Flushing, borough of an inch. Each of these breast size scales of Queens, in the county of Queens and 'l has its principal divisions numbered from 12 60 State of New York, have invented a new to 24, and the numeral designating the diand Improved Tailors Square, of Which the vision is one-half of the Whole breast size of following is a full, clear, and exact descrip- Which the length from the end of the square tion. l to the division bearing the numeral is the The invention relates to drafting and l proper fraction.

In a like part of the same; Fig. 3 is a diagram repremanner the supplementary scale D for the S5 senting a portion of the lines for laying olil eighths of the half breast measure on the a coat from back center to front center. short arm A, is continued along the scale O The tailors squares, as heretofore ccnfor fourths of the half breast measure, and

But each of use of such square to obtain the divisions said scales O and D for a particular fraction of breast sizes for persons of a larger breast of the half breast measure include all frace circumference than 4S inches. ln such cases tions from the smallest size to the largest 4C the tailor had to resort to considerable size met with in practice. 95 calculation in order to obtain the desired It Will be understood that in laying off a result. To overcome this difliculty and to garment, the breast measure is the basis, and

permit the use of the square for obtaining the remaining dimensions are proportioned divisions of breast sizes up to the largest size to the special breastmeasurement. ln laying' met With in practice, say up to 96 inches, off a garment, the commencing line is along 100 is the object of the invention presently to be the center of the back, and the basis for the described in detail. pattern is aline along the said center, in length The short and long arms or legs A and A one-third of the half breast measure. The

of the tailors square shown in Figs. 1 and 2 scales O, C are so arranged that the numerals are provided along the inner margins with thereon Will be opposite the numerals on the the usual inch scales B and B', and along scales B B, Whichcorrespond to the third of the outer margins are arranged the ordinary the numeral on the scales O C', as for instance, breast-size scales O, C', expressed in fracin Fig. 2, the numeral 24 on the scale C corretions of inches as units. Thus the scales O spends With the position of the numeral 4 on the short arm A have as units halves, in the scale of sixths, 4 being one-sXth of 11C Cri 24. In the scale of Srds, the numeral 6 on the scale B, corresponds to the position of the numeral 18 on the scale C', being fg of 18. In laying off the garment, the basis as before stated is one-third of the half of the lrnown breast measure, which in a 36 inch breast measure for instance, would be 6 inches. To this an arbitrary quantity is added to carry the length desired for the half length of the coat. 'lhis arbitrary quantity of course depends upon the fashion, and upon the relative height ofthe individual. l" rom the line formed by the base, and the arbitrary quantity, the half garment (t. e., half Width) is laid ofl', as the pattern is drafted for one side only. The line A-D inFig. 3 is always one-twelfth of the half breast size, and the line D-E is an arbitrary addition depending as before stated upon the peculiarities of the individual, and of the fashion. The line l-F, is i'ive-eighths of an inch also an arbitrary quantity. 'ihe line CMG is one-fourth of the half breast measure, and the line Gf'l'l is an arbitrary addition for the same reason stated for the lines A, D, and D From H to l is one-eighth of the half breast measure. T he remainder of the pattern is laid off in the same manner, certain portions ofthe lines being in one-thirds, one-fourths etc. ofthe breast measure, and other portions arbitrary, lengths, depending as previously stated upon the fashion prevailing and upon the pecul iarities of the individual for whom the garment is designed. As before stated tailors squares have been arranged up to a8 inches, but in order to obtain the proportionate measures for larger sizes, it was necessary to calculate such measurements, and after-- Ward lay them off. The scales D, D carry the calculations forward, thus dispensing with the necessity for calculation.

It will be observed, that the division lines on the scales D, D corresponding to the breast sizes of the supplementary scale are arranged in alinement with the divisions marking the fractions of inches. As, for instance, the breast size 6() corresponds in position with the line marked 5 in the inch scale. One-half of is 30, and one-third of 30 is l0, which is twice 5. This relation will be found throughout the scales, that is the numeral designating the division on the inch scale will correspond to a breast size whose half measure is three times twice the numeral. ln laying off from the suppleinentary scale, instead of laying oif a number of inches corresponding to the position of the breast size, double such number of inches as laid off.

ln Fig. 3, the line A, B represents onethird of the half breast measure, and the line B, C represents the arbitrary quantity added to compensate for differences, and the said line A, B is the base from which the other measurements are laid off.

Having thus described my invention, l claim as new and desire to secure by Letters Patent:

l. A tailors square having an arm provided on one edge with a scale of inches and fractions thereof, and on the other edge with a scale of various fractions of usual half breast sizes, the divisions marking the half breast sizes, being arranged in alinement with the appropriate divisions of the other scale, and a supplementary scale intermediate the two scales, the divisions of the supplementary scale, being in alinement with divisions of the first scale corresponding to half the appropriate fraction.

2. A tailors square having an arm provided with a scale of inches and fractions thereof, and with a scale of various fractions of usual half breast sizes, the divisions marking the half breast sizes, being arranged in alinement with the appropriate divisions of the other scale, and a supplementary scale, the divisions of the supplementary scale being in alinement with divisions of the first scale corresponding to half the appropriate fraction.

ln testimony naine to this specification in two subscribing witnesses.
